SPECIFICATION forming part of Letters Patent No. 419,723, dated January21, 1890'.

To all whom iv may concern.-

Be it known that I, HENRY SKINNER, engineer, a subject of the Queen ofGreat Britain, residing at 43 Singlewell Road, Gravesend, in

the county of Kent, England,.have invented certain new and usefulImprovements in Blowers, Pumps, Engines, and Meters, (for which I havereceived Letters Patent in Great Britain, No.10,964:, dated July 28,1888; in

[0 France, No. 196,236, dated February 22, 1889; in Belgium, No. 85,117,dated February 22, 1889, and in Germany, No. 48,848, dated February 26,1889,) of which the following is a specification.

My invention relates to rotary engines of that class in which acylindrical outer casing closed at each end and provided with inlet andoutlet ports has Within and parallel with, but eccentric to it, a secondcylinder or axle and blades or flaps bridging the space between thecasing and this inner cylinder or axle, and which are hinged at one endto the inner cylinder or axle, and at their opposite end are held alwaysclose to the inner circumference of the casing;

The objects of my invention are to prevent leakage and to avoid unduefriction in engines of this kind. These I attain as follows: To hold theouter ends of thefiaps in close proximity to the inner circumference ofthe casing 1 joint the outer ends of the flaps to pins or supportscarried by a disk, which is at one end of the casing and is on a shaftconcentric with it, while the inner ends of the flaps I joint tocylindrical thimbles, which are set side by side and are free to turn onan aXle which is eccentric to the casing.

In the accompanying drawings, which represent so much of an apparatusembodying all my improvements as is necessary to illustrate thesubjectmatter herein claimed, Figure 1 is a transverse section, Fig. 2 alongitudinal section, and Fig. 3 an elevation, of the inner cylindricalthimbles set at a distance apart.

A cylindrical outer casing A is shown as provided with inlet and outletports 0 C, respectively situated on opposite sides thereof in line witheach other. Cylindrical thimbles (No model.) Patented in England July28, 1888, ilox 10,964: in France No.196,236; in Belgium February22,1889, No. 85,117, and in Germany February 26, 1.889, No. 48,848.

E fit loosely side by side on an axle F, fixed at one end to one of theheads of the outer casing, to which it is eccentric. Blades or flaps Dare jointed at one end to these cylinders and at the other to pins J,projecting laterally from the inner face of a disk J, fixed on a shaftK, passing through one of the heads of the casing. This shaft can eitherdrive the disk or segments and blades or flaps or be driven by them, asneedful. The outer ends of the flaps carry slipper-pieces N, fittingthem and the interior of the outer casing to make a tight joint. Theseslipper-pieces may either be loose and free to turn somewhat on the endsof the flaps, or they might be fixed to the disk J and then formbearings for the outer ends of the flaps to turn in. The flaps not onlybridge the space between the thimbles B and the casing, but extend fromend to end of the latter, so as to make a tight joint at the ends, aswell as at their outer and inner sides. Each cylindrical thimble B isformed with an arm standing out from it and extending from end to end ofthe casin g, and the portion of the arm which extends beyond the thimbleis made to fit closely to the circumference of the other thimble, so asto obstruct the passage of fluid between them. The flaps are jointed tothese arms. The joint is shown as made by inserting the enlarged roundedend of the flap endwise into a correspondinglyshaped groove in the arm.

The above figures show two flaps only, but three or more flaps jointedto three or more cylindrical thimbles maybe used with good effect.

If three or more flaps are used, the inlet and outlet ports of the outercasing need not be opposite to one another, but might be in othersuitable positions relatively to one another so long as their distanceapart is such that the direct passage between them is always closed byone or other of the flaps.

The operation of the apparatus will be readily understood from theforegoing description. The flaps being jointed at their 95 inner ends tothe cylindrical thimbles, these thimbles are made to rotate around theshaft F whenever the disk J, to which the outer ends of the flaps arejointed, is made to rotate, and each thimble being free to turnindependently of the other or others permit of the free movement of theflaps.

Having thus fully described the construc tion, organization, andoperation of my improved apparatus, What I claim therein as new andot'my own invention is The combination, substantially as hereinbefore setforth, of an outer casing provided with inlet and outlet ports,cylindrical thinnbles inclosed therein and set side by side on an axleeccentric thereto, a disk Within the casing and at one end thereofcarried by a shaft concentric with the outer casing, and flaps jointedat their opposite ends to the cylindrical thiinbles and to pins orbearings carried by the disk, respectively.
